An increasing temperature and reducing precipitation scenario along with other environmental factors, contribute to increased evapotranspiration, negatively affect growing season, leads to lower crop yields especially of Zambia’s staple food crop maize and seriously threatens national food security with the poor rural …
How has climate change affected agriculture in Zambia?
Food Security
As agricultural and livestock production are largely dependent on rainfall, the country’s high rainfall variability and limited irrigation capacity make them vulnerable to climate change. The rising frequency of drought and shorter rainy seasons has led to increasing crop loss and food insecurity.
How is Zambia affected by climate change?
Changes in climate pose challenges to Zambia’s ongoing efforts to combat poverty, reduce food insecurity and sustainably manage natural resources. Climate projections in Zambia include increases in temperature and more extreme weather (intense precipitation, floods and droughts) and increased rainfall variability.
How does climate change affect farming and agriculture?
Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.
What are two ways that climate change is affecting agriculture?
Climate change impacts
Sea level rise is also ratcheting up the frequency and intensity of flooding on farms in coastal regions. These costly floods devastate crops and livestock, accelerate soil erosion, pollute water, and damage roads, bridges, schools, and other infrastructure. Droughts.

Which two climatic factors are mainly affected by altitude?
Temperatures, air pressure and air density decrease with altitude (about 32,9°F to 33,8°F (0,5°C to 1°C) every 100m). Winters are cold and summers are cool and wet. Rainfall is most important according to altitude.
What are the main impacts of climate change?
Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
What is the impact of human activities on the climate?
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
What factors influence climate in Africa?
The most important natural factors are:
- distance from the sea.
- ocean currents.
- direction of prevailing winds.
- shape of the land (known as ‘relief’ or ‘topography’)
- distance from the equator.
- the El Niño phenomenon.

Which crops will be affected by climate change?
Using an aggressive climate model known as HadGEM2, researchers at the International Food Policy Research Institute project that by 2050, suitable croplands for four top commodities—corn, potatoes, rice, and wheat—will shift, in some cases pushing farmers to plant new crops.
Do farmers believe in climate change?
Thirty-five percent of farmers indicated belief that extreme weather would become more common in the future. On the other hand, 33% agreed that climate change is not a big issue because human ingenuity will enable us to adapt to changes. Results showed substantial levels of support for both adaptation-related items.
How climate change will affect food production?
Climate change affects food production and availability, access, quality, utilization, and stability of food systems. In short, it impacts all aspects of the food system. Extreme weather-related disasters are increasing and reduce the yields of major crops. Higher levels of CO2 reduce the nutritional value of crops.
